  When attending a live concert, fashion show, comedy show or any other event--a master or mistress of ceremonies (MC) is usually at the helm, ensuring smooth progression between acts and sets. While wearing snazzy attire and introducing entertainers might be all the audience knows an MC for, there is much more to this role.
  
  

Perform a Sound Check

• Approximately 30 to 45 minutes before the start of the show, a well-prepared MC should be available to perform a sound check to ensure the microphone works properly and that speakers are set to an appropriate volume.
  
  

Set Expectations

• A good MC gives the audience an idea of what will take place during the show and the duration of the show. When new acts are being introduced, an experienced MC provides background information (such as the act's hometown) on each performer to create a rapport between the audience and the entertainer. He also solicits applause at the conclusion of each act to keep energy levels high throughout the show.
  
  

Know Names

• There is nothing worse than mispronouncing or forgetting the names of acts you are introducing. A good MC finds out the correct pronunciation of all acts and special guests she will announce days before the show, when possible.
  
  

Gauge the Audience

• The MC determines how receptive and attentive the audience will be toward entertainers. In response to a less receptive audience, the MC might crack a joke or interact with the audience to build overall enthusiasm. Audiences who already generate great enthusiasm make the job of an MC fairly easy, and the MC in this case just has to announce the next act or next segment and move along.
  
  

Announce Changes in the Program

• Although detailed programs are sometimes distributed to an audience upon their arrival, plans can change at the last minute. Acts cancel or run late; band members get sick. In either case, a good MC is prepared to announce these changes while reassuring the audience to stay and enjoy the new show lineup.
  
  In addition, there are times when building evacuation is necessary during a show. At these times, the MC points out the nearest exits and ensures the audience leaves the building in an orderly fashion. The security team and other staff can assist with this effort. The MC also makes sure information on reentering the building is provided, along with ticket refund information when applicable.
  
  

Summarize/Conclude the Event

• Once the show has concluded, an MC thanks the audience for participating. In addition, he might mention a few upcoming events, ask all acts to return to the stage to take a bow and request donations or promote merchandise that is for sale.
